In a SPIEGEL interview, French social scientist Emmanuel Todd discusses the demographic roots of the Arab revolution, which he argues was spurred by rising literacy and rapidly shrinking birth rates. He also muses on the ghost of Osama bin Laden, arguing "al-Qaida was already dead," and on why he believes Germany is not a part of the "core West."

SPIEGEL: Monsieur Todd, in the middle of the Cold War, in the days of Leonid Brezhnev, you predicted the collapse of the Soviet system. In 2002, you described the economic and imperial erosion of the United States, a global superpower. And, four years ago, you and your colleague Youssef Courbage predicted the unavoidable revolution in the Arab world. Are you clairvoyant?

Todd: The academic as fortune-teller -- a tempting idea. But Courbage and I merely analyzed the reasons for a possible -- or let's say likely -- revolution in the Arab world, an inexorable change, which could also have unfolded as a gradual evolution. Our work was like that of geologists who compile the signs of an imminent earthquake or volcanic eruption. But when exactly the eruption takes place, and its form and severity -- these things cannot be predicted in an exact way.

One interesting point in the long interview is Todd's contention that the European parallel for the Arab Spring is not 1989 but 1848.
